It might begin with a table lamp. Tap the shade, give it a spin. Turn the entirelamp, watchingthe red of its body blot out the yellow of the shade—and then the other way arounduntil all the red disappears, drowned in yellow. Keep turning, and you have a lightbulb. Tap it, and it blazes with green light. Turn it just right, until the green becomes just a formless circle, and you have a bowl. Or a guitar! Or, really, it could be anything at all.
